Detailed Description

Header file for SHA-2 cryptographic hash functions.

This header file defines the interface for the SHA-2 family of hash algorithms, including SHA-224, SHA-256, SHA-384, SHA-512, SHA-512/224, and SHA-512/256.

It provides macro definitions for block and digest sizes, context structures for maintaining the hash state, and declarations for functions that perform the core transformations, initialization, updating, finalization, and one-shot hash computations. The implementation adheres to the standards specified in FIPS 180-4.

Note: The SHA-2 algorithms defined in this file process data in fixed-size blocks and output a fixed-length digest. They are designed for high performance and security in cryptographic applications.

See also: https://nvlpubs.nist.gov/nistpubs/FIPS/NIST.FIPS.180-4.pdf for further details on SHA-2.

		ha_inbuf_t	data )

Transforms the data in the SHA-2 512-256-bit context.

This function performs the transformation step of the SHA-2 512-256-bit hash computation. It processes the input data block and updates the internal state of the context.

Parameters

ctx	Pointer to the SHA-2 512-256-bit context structure.
data	Pointer to the input data block (128 bytes).

◆ ha_sha2_512_256_update()

HA_PUBFUN void ha_sha2_512_256_update	(	ha_sha2_512_256_context *	ctx,
		ha_inbuf_t	data,
		size_t	length )

Updates the SHA-2 512-256-bit context with new data.

This function processes the provided data and updates the SHA-2 512-256-bit context state.

Parameters

ctx	Pointer to the SHA-2 512-256-bit context structure.
data	Pointer to the input data to process.
length	Length of the input data in bytes.

◆ ha_sha2_512_final()

HA_PUBFUN void ha_sha2_512_final	(	ha_sha2_512_context *	ctx,
		ha_digest_t	digest )

Finalizes the SHA-2 512-bit computation and produces the hash digest.

This function finals the SHA-2 512-bit hash calculation and outputs the resulting digest into the provided buffer.

Parameters

ctx	Pointer to the SHA-2 512-bit context structure.
digest	Pointer to the output buffer to store the final SHA-2 512-bit digest (64 bytes).

◆ ha_sha2_512_hash()

HA_PUBFUN void ha_sha2_512_hash	(	ha_inbuf_t	data,
		size_t	length,
		ha_digest_t	digest )

Computes the SHA-2 512-bit hash in a one-shot operation.

This function computes the SHA-2 512-bit hash of the provided data in a single call. It initializes, updates, and finals the SHA-2 512-bit computation internally.

Parameters

data	Pointer to the input data to process.
length	Length of the input data in bytes.
digest	Pointer to the output buffer to store the final SHA-2 512-bit digest (64 bytes).

◆ ha_sha2_512_init()

HA_PUBFUN void ha_sha2_512_init ( ha_sha2_512_context * ctx )

Initializes the SHA-2 512-bit context.

This function initializes the SHA-2 512-bit context to start a new hash computation.

Parameters

ctx	Pointer to the SHA-2 512-bit context structure to initialize.

◆ ha_sha2_512_transform()

HA_PUBFUN void ha_sha2_512_transform	(	ha_sha2_512_context *	ctx,
		ha_inbuf_t	data )

Transforms the data in the SHA-2 512-bit context.

This function performs the transformation step of the SHA-2 512-bit hash computation. It processes the input data block and updates the internal state of the context.

Parameters

ctx	Pointer to the SHA-2 512-bit context structure.
data	Pointer to the input data block (128 bytes).

◆ ha_sha2_512_update()

HA_PUBFUN void ha_sha2_512_update	(	ha_sha2_512_context *	ctx,
		ha_inbuf_t	data,
		size_t	length )

Updates the SHA-2 512-bit context with new data.

This function processes the provided data and updates the SHA-2 512-bit context state.

Parameters

ctx	Pointer to the SHA-2 512-bit context structure.
data	Pointer to the input data to process.
length	Length of the input data in bytes.
